As we move forward, sustainable and renewable energy is becoming increasingly important. More and more companies and businesses are trying to use solar and wind energies to supplement their fossil fuel intakes. The general public, on the other hand, has a much more limited access to sustainable energies. Sustainable Systems of Colorado is a non-profit organization that works to promote sustainable energy within Colorado. Two of their biggest projects have been SkyTran, a monorail system that runs on solar and hydraulic energy, and the Sustainable Smart Home which is a renovated home that uses a variety of modern and old technologies that are based around renewable resources.
